dc.description	The A-Pool is located in south eastern part of Hamada-NC8A in Ghadames Basin, eleven wells has been drilled during the exploration appraisal phase. Seven wells (A1- NC8A, A6-NC8A, A7-NC8A, A8-NC8A, A9-NC8A, A11-NC8A & A12-NC8A) considered oil wells, where as (A2-NC8A, A3-NC8A, A4-NC8A and A5-NC8A) were dry, the Tadrart sandstone Formation represent the main petroleum play within the southern part of the Ghadmes Basin, it is composed of a series of non-marine to marginal marine sediments, the sandstones reservoir interpreted to be channel deposits, including fluvial channels and tidal estuarine channels. Tadrart Formation has been divided into Tadrart-D1 and Tadrart-D2. Tadrart-D1 subdivided into Tadrart-D1b, Tadrart-D1aSH and Tadrart- D1SH, the Tadrart-D1b represent the main reservoir composed of estuarine, tidal creek, tidal sand flats and shore face deposits, the depositional environments identified through core descriptions in APool were compared with the log signatures and petrophysical analysis . The Tadrart thickness map were generated by using well tops shows clearly variable gross formation ranging from 55 to 260 feet, petrophysical analysis identified the net pay thickness of the Tadrart-D1b ranging from view feet to 80 feet, porosity reached up to 16%, water saturation reached up to 49% and the volume of shale reached 16%. The Tadrart-D2 with maximum thickness of 45.5 feet, porosity ranging from (7 to17%), water saturation ranging from (35 to 56 % ) and Volume of shale reached up to 14%
